filter press
Description
Sludge Dewatering Belt Filter Press is a common type of mechanical
dewatering equipment. Which is widely used for efficient dewatering
of sludge from municipal, industrial, mining and aggregaes
wastewater treatment plants. Especially suitable for dewatering of
tailings mud such as iron ore, copper ore, lead-zinc ore, fluorite
ore, bauxite or rare earth ore; Dewatering operations such as ore
dressing wastewater, sand washing mud or wash plant sludge.
The slurry is sandwiched between two tensioned porous belts, by
passing those belts through a serpentine of decreasing diameter
rollers. Water is then removed from the slurry and a solid material
is produced.
Working Principle
1. Thickener dehydration: chemical pretreatment stage
The belt filter press has higher requirements for flocculation
effect. This machine uses a unique dosing mixer to achieve rapid
flocculation and achieve the best flocculation effect.
2. Gravity dehydration: gravity concentration dehydration stage
The sludge is evenly fed into the mesh belt through the cloth
bucket. The sludge runs forward with the filter belt. The free
water flows into the water tank through the filter belt under the
action of its own weight. The main function is to remove the free
water in the sludge, so that the fluidity of the sludge is reduced
and ready for further extrusion.
3. Low/medium pressure dewatering: wedge preloading dewatering
stage
After gravity dewatering, it is still difficult to meet the sludge
flowability requirements of the press dewatering section. After
this stage of slight extrusion dewatering, the sludge is smoothly
pressed and dewatered.
4. High pressure dehydration: the depressurization stage of the
clamp press
The filter cake is repeatedly pressed and sheared around the press
roll by the upper and lower filter belts. A large amount of
capillary action water is removed to gradually reduce the moisture
of the filter cake.
Features
1. Belt press has an easily adjustable and variable wedge
compression zone that maximizes process rate and performance.
2. Suitable for all types of organic sludge and inorganic mud,
municipal WWTP sludge, pulp &paper sludge, water plant sludge.
3. The belt press is constructed with a stainless steel structure
and rollers, durable for more than 10 years .
4. Low power is needed to run the belt filter presses. With long
term value and ease of operation.
5. Compact footprint, 4-stage dewatering and automated operation

Belt Press Applications
Belt filter presses are designed for dewatering applications where
sludge is particulate, include various types of industrial
wastewater sludge, such as sand-making mud, washed sand mud, mine
tailings, piling mud, river silt, etc. They are pumped to the deep
cone thickener, the flocculant is added to the thickener tank, and
the concentration of the sludge in the thickener is increased by
60%-70% under flocculation and gravity precipitation. Then sent to
the belt filter presses, under the action of a gravity zone, a
wedge zone, and a pressure zone , the sludge cake with water
content of less than 20% is formed and the overflow clean water
will be re-processing.
